BUM PER.

Application filed''uly 18, 1919. Serial No. 311,744.

To all whom it may concern:

Be it known that I, ALEXANDER L. EVANS, a citizen of the United States, residing at Fort Vayne, in the county of Allen and State of Indiana, have invented new and useful Improvements in Bumpers, of which the following is a specification.

This invention relates to railway bumping posts.

The main object of the inventionis to provide a substantial and extremely rigid bumping post constructed of reinforced concrete in such a manner that the same will withstand heavy shocks without danger of injury and which may be constructed at relatively small expense.

Other objects and advantages will appear as the nature of the invention is better understood, reference being had to the accompanying drawings, illustrated a simple and satisfactory embodiment of the improvement reduced to practice, and in which: p I

Figure 1 is a side elevation or a bumping post embodying my improvement.

Fig. 2 is a top plan view thereof.

Fig. 3 is a front elevation thereof.

Fig. 1 is a sectional view approximately on the line H of Fig. 2.

Fig. 5 is a perspective view of one of the vertical reinforcing bars or rods.

Fig. 6 is a similar view of one of the angle reinforcing bars or rods.

Fig. 7 is a transverse sectional view approximately on the line 77 of Fig.1

The bed of my improvement is constructed of concrete and is designated by the numeral 10. Extending longitudinally through the concrete bed 10 are reinforcing rods 11. These rods are arranged in horizontal series in the bed and are disposed in relation to each other so that the bed will be amply reinforced throughout the length thereof. 1 P

Arising from the bed, and also formed or concrete is a bumper post 12. This post is disposed a suitable cistance inward of the outer end of the bed. Embedded vert cally in the post 12 are rods 13 arranged in longitudinal spaced series, and these rods are disposed close to each other but are disposed to one of the sides of the series of rods 11 in the bed.

For distinction the upper series of rods in the bed are indicated by the numerals 14:, the intermediate series by the numerals 15 in which there is] and the lower series. by the'numerals 16. The rods may be straight or bent upon' in the construction of the post, while three series of such rods are employed in the construction of the bed, but, of'course, any de sired number of such rods may be employed 1 in the construction of the device, it being desirable that a greater number be used in reinforcing the post than the bed, and the rods of the post have their inner endsliooked, as at 21 to engage with the longitudinal and horizontally disposed series ofieinforcing rods in'the bed. The hooks 21 V on the series of rods 17 engagewith-the lower series of rods 16 in the bed. The rods 18, from the nearest inner series' to the outer rods 17 have their hooked ends engaged with the upper series of rods 11 of the bed. The

next vertical series of rods 19'have their hooked ends engaged with the intermediate series of rods 16 of the bed, while the lastor outermost series of reinforcing rods 20' for the post have their hooked ends engagedwith the upper rods 14 of the bed 10.- It will be thus seen that the post is effectively tied to the bed so that any shock received by the post will be absorbed or takenup bytherod connection between the post and bed.

Angle reinforcing rods 22 are employed at the front of the post construction. These rods have both their ends hooked as at 23,

one of the hooked ends engaging with the rods 17 of the post and the other hooked end engaging with the rods 14 of the bed. The lower portion of the post, at its connection with the bed is arranged at an angle as indicated by the numeral 24;, and within this angle portion is embedded a series of rods 25 which enter the bed 10, the said rods having their ends hooked as at 26 to engage with the'reiiiforciiig rods in the bed.

The rails for the cars are indicated by the numerals 27 and rest on ties 28 that are arranged on the upper horizontal straight face of the bed 10. These rails may enter the post 12 and have their ends received in the said post curved between certain of the reinforcing rods 13 in the said post.

On the front face of the post 12 is arranged a transversely disposed wooden block 29, the securing elements wherefor being in Specification of Letters Patent. I Patented--DeC, i6, 191 9.

the nature of bolts 30 that pass entirely through the post 12 between the reinforcing rods therefor, nuts engaging the said bolts. Centrally secured on the block 29 is a metallic plate 31, certain of the securing bolts passing through the plate as Well as the block and post for retaining the plate on the block.

It is believed, from the foregoing description, when taken in connection with the drawings, that it will be seen that I have produced a simple, cheap, strong and eflective device for the purpose intended and one which will withstand a greater amount of shock or jar than any other construction of such devices with which I am acquainted. The wooden block 29 and the metallic plate 30, incident to the strain to which they are subjected are necessarily removable for replacement when damaged, and to provide for this the post 12 has sleeve members passing therethrough which are indicated by the numerals 50. These sleeves are, of course, embedded in the post in the course of con struction of the device and the securing bolts for the plate and block pass through these members 50. It will be obvious by detaching the nuts that connect the bolts, the latter may be readily removed from thepost.

Having thus described the invention, what is claimed as new, is

l. A bumping post for railway rolling stock including a concrete structure comprising a bed and a post arising from the bed adjacent one end thereof, series of horizontally disposed longitudinally extending reinforcing rods in the bed, series of vertically disposed reinforcing rods in the post and entering the bed, said last mentioned reinforcing rods having their inner ends hooked and said hooks being arranged in staggered engagement with the reinforcing rods of the bed. 7

2. In a bumping post for railway rolling stock, a bed constructed of reinforced concrete and a post also constructed of reinforced concrete arising from the bed, said bed having a plurality of longitudinally disposed horizontally arranged reinforcing rods therethrough, said post having a plurality of vertically disposed longitudinally arranged reinforcing rods therein, said rods entering the bed and having their ends hooked and staggeredlyengaging with the reinforcing rods of the bed, and angle reinforcing rods at the lower portion of the front of the post having hooks thereon engaging with the outer series of vertically disposed reinforcing rods and with the upper series of horizontally disposed reinforcing rods.

3. A bumping post for railway rolling stock including a bed and a post arising inward of one end of the bed, both constructed of concrete having reinforcing rods therethrough, the reinforcing rods of the post entering the bed and being locked to the reinforcing rods for the bed, and angle reinforcing rods between the bed and post and connected with certain of the reinforcing rods of both the bed and post, the post having an angle lower portion, reinforcing rods therein having their lower ends hooked and engaging with certain of the reinforcing rods for the bed, a wooden plate arranged transversely over the face of the post, a metal plate arranged centrally on the outer face of the wooden plate, and securing elements for said plates passing through the posts between the reinforcing rods therefor.

In testimony whereof I my signature.

ALEXANDER L. EVANS.
